With the batteries in these modern smartphones, they have proven to be far more reliable than their old counterparts, but one can't afford to be so vigilant. A bad battery ruins otherwise excellent performance from the Galaxy phone.

Thankfully, checking the battery health on your Galaxy device may save you from problems later down the road.

Why Monitor Your Battery Health

How to Know Your Samsung Phone's Battery Health

More people than ever are holding onto their Galaxy devices a lot longer than they might otherwise because of longer support periods. And more extended usage means increased pressure on the battery. And even though newer models like the Galaxy S21 Ultra do not show extreme differences from year to year, this battery health is still one to consider.

After many years, your Galaxy's battery can degrade and this will affect the battery life. You will also experience performance issues like sudden lags and screen freeze. If you're worried about your device's battery, immediately check its status to avoid issues.

Checking Galaxy Phone Battery Health in the Samsung Members App

In Samsung, it's easier to monitor the battery health of your phone. With the Membes app, you're just a few clicks away from seeing it.

1. Open the Samsung Members app on your Galaxy phone.
2. Tap "Support" at the bottom of the screen.
3. Choose the "Phone Diagnostics" card to explore diagnostic tools.
4. Scroll down and tap "Battery Status" to check the health of your battery.

When you run the diagnostic tool, the application will give you a rough summary of your battery's present status and its total capacity.

If your battery still has a condition above 80% of its original capacity, it's in good condition. But if anything falls below that, you may have to change it.

Using a Secret Dial Code to Test the Condition of Your Battery

Besides the Samsung Members app, you can check your battery health with an Android diagnostic code. It works on most phones but is not a guarantee. Follow these steps:

1. Open the Dialer app on your phone.
2. Input the diagnostic code: *#*#4636#*#*.
3. After entering the code, your phone will automatically open a menu.
4. Look for Battery Information. If it's available, you'll be able to see key details like your battery's health, charge level, and temperature.

This method works on devices like Xiaomi, OnePlus, and Google Pixel phones, but it might not be available on all Samsung devices. If it doesn't work, don't worry—Samsung's Members app is a reliable alternative.

What to Do If Your Battery Health Is Poor

If you find that the battery on your Galaxy smartphone is badly degraded and requires replacement, do not despair. For, with Samsung in collaboration with iFixit, such replacement has now become simpler for users.

iFixit sells do-it-yourself kits that provide all that is needed to replace the battery, along with the requisite tools; prices start at $30 just for the battery itself.

A more thorough fix, like a screen replacement or battery replacement, could add up to be really pricey, such as a Galaxy S22 Ultra kit costing $239.

If you're not keen on DIY repair, then visit a Samsung service center to have your phone professionally repaired. Whichever route you choose, checking your battery health is the first step toward making sure your Galaxy phone runs in top shape.

Signs Your Galaxy Phone's Battery May Need Replacing

Not always easy to tell that your battery is deteriorating, but there are a few signs to look for. For example, if your phone shuts down unexpectedly, even though there is still battery power left, this may indicate a problem.

If your battery drains much faster than usual, it is also time to check its health.

In colder temperatures, you may find that battery performance drops more rapidly. You may also find that power-hungry apps such as games or camera apps will cause the battery to drain faster. If you are experiencing these problems, it is a good idea to get your battery checked.

Keeping Your Galaxy Phone Running Strong

Maintaining a healthy battery is the key to keeping your Galaxy phone in top condition. It will be able to check on your battery health through the Samsung Members app or by dialing a secret code.

That way, you will know if it is deteriorating, and changing it is pretty simple; you can even do it with iFixit or by using a professional repair service. So long as you treat your Galaxy phone right, it will serve you for many years.
